Impact of sucrose sinks on phloem transport Open
The movement of photosynthates within plants is a focus in plant physiology, ecohydrology, and earth systems modeling. The phloem, one of the plant’s hydraulic systems, facilitates this transport. It is believed to be optimized for efficie…

Discounting Water for Optimal Carbon Gain as a Basis of Stomatal Closure Open
The exchange of carbon dioxide and water vapor between terrestrial ecosystems and the atmosphere is regulated by stomata (small pores in the leaves of plants). Unsurprisingly, environmental factors controlling the opening and closure of st…

Sucrose transport inside the phloem: Bridging hydrodynamics and geometric characteristics Open
In plants, the delivery of the products of photosynthesis is achieved through a hydraulic system labeled as phloem. This semi-permeable plant tissue consists of living cells that contract and expand in response to fluid pressure and flow v…

Toward a Realistic Representation of Sucrose Transport in the Phloem of Plants Open
The significance of phloem hydrodynamics to plant mortality and survival, which impacts ecosystem‐scale carbon and water cycling, is not in dispute. The phloem provides the conduits for products of photosynthesis to be transported to diffe…

Taylor Dispersion in Osmotically Driven Laminar Flow in Phloem Open
Sucrose is among the main products of photosynthesis that are deemed necessary for plant growth and survival. It is produced in the mesophyll cells of leaves and translocated to different parts of the plant through the phloem. Progress in …

A Dynamic Optimality Principle for Water Use Strategies Explains Isohydric to Anisohydric Plant Responses to Drought Open
Optimality principles that underlie models of stomatal kinetics require identifying and formulating the gain and the costs involved in opening stomata. While the gain has been linked to larger carbon acquisition, there is still a debate as…
